I am looking for some advice.

My organisation currently has ZenWorks 6 Suite which I think contains
ZenWorks Desktop v4.

What are the differences between ZenWorks Desktop v6.5 and Zenworks
Dekstop v4 and is there any new features worth having.

Also is there anywhere I can find a document that will explain and
highlight the differences between Zenworks 6 Suite and Zenworks 6.5 Suite.

Get back to me as soon as possible please.
